Three cameras along 71st Street and Kedzie in the Marquette Park area went live at approximately 6 a.m.

City officials say the intent of the cameras is to change a culture that suggests speeding is tolerated. Speed cameras have been put into place in school and park zones where high accident rates have been reported.

The city's first speed camera started issuing tickets on Wednesday to those who go 10 miles or over the speed limit near Gompers Park on the Northwest Side.

According to officials, fines from speed camera tickets are projected to bring in $40 million to $60 million. That revenue, the city says, will go to traffic safety improvements and after school programs.

Critics say Chicago Mayor Rahm Emanuel is just trying to balance the budget on the backs of drivers.

Those caught driving 10 miles per hour over the speed limit will be fined $100. Eventually, drivers going between 6 and 10 mph over the speed limit will also get tickets and will have to pay a $35 fine.

Four more speed cameras going online by the end of the week.

A total of 50 cameras will be up and running in the next 12 months. Addresses below are those of the parks and schools around which the cameras will be installed, not of the specific camera locations:
